Tattooing and hepatitis B infection.

To determine the prevalence of HBV carrier status in tattooed persons, 200 healthy, tattooed volunteers and 200 non-tattooed volunteers to match the first group for age, sex and ethnic group were screened. Prevalence of HBsAg in tattooed and non-tattooed volunteers was 19.5 and 9% respectively, which was a statistically significant difference (P less than 0.01). There was no difference in the prevalence in various age groups, ethnic groups, or sex, between the two groups.
